RCON Register

The RCON register contains flag bits which are used to

determine the cause of the last Reset or wake-up from

Idle or Sleep modes. RCON also contains the IPEN bit

which enables interrupt priorities.

The operation of the SBOREN bit and the Reset flag

bits is discussed in more detail in Section 4.1 “RCON

IPEN: Interrupt Priority Enable bit

1 = Enable priority levels on interrupts

0 = Disable priority levels on interrupts (PIC16XXX Compatibility mode)

bit 6

SBOREN: Software BOR Enable bit(1)

For details of bit operation, see Register 4-1.

Note 1: Actual Reset values are determined by device configuration and the nature of the

device Reset. See Register 4-1 for additional information.

bit 5

Unimplemented: Read as ‘0’

BOR: Brown-out Reset Status bit

For details of bit operation, see Register 4-1.

Legend:

R = Readable bit

W = Writable bit

U = Unimplemented bit, read as ‘0’

-n = Value at POR

‘1’ = Bit is set

‘0’ = Bit is cleared

x = Bit is unknown
